Abstract

L'invention concerne une source de lumière pour transmission proche infrarouge et spectroscopie de réflexion qui peut être construit à partir d'une combinaison d'une diode électroluminescente (DEL) bleue ou bleue-verte haute puissance et un élément phosphorescent à base d'un matériau inorganique. L'élément phosphorescent absorbe la lumière de la DEL et, en réponse à l'excitation de la DEL, émet une luminescence qui couvre de manière continue la plage 700-1050 nm. Un matériau possible qui peut être utilisé pour un tel élément phosphorescent émettant dans l'infrarouge proche est une tige monocristalline de saphir dopé au Ti+3. Un autre matériau phosphorescent émettant dans le proche infrarouge est un composite en forme de disque ou rectangulaire de poudre de Saphir dopé au Ti +3 incorporé dans un agent d'encapsulation silicone ou époxy optique transparent. Une telle combinaison d'une DEL bleue pour l'excitation d'un élément phosphorescent qui émet dans une large bande de longueur d'onde a été largement utilisée dans des DEL blanches où l'émission est dans la plage de 400 à 700 nm.
